Abstract (en)
Disclosed is a turboengine. The turboengine comprises an outer wall structure (11) and an inner wall structure (12), wherein the inner wall structure is provided at a radially inner position with respect to the outer wall structure, and each of the wall structures (11, 12) comprises a surface, said surfaces being arranged facing each other in the radial direction. A duct (14) is provided between the inner wall structure and the outer wall structure and having a downstream end with respect to a main working fluid flow direction of the turboengine. At least one guide vane member (20) is arranged at the downstream end of the duct, the guide vane member (20) comprising at least one airfoil, a radially inner end and a radially outer end. The inner end of the guide vane member is supported at the inner wall structure and the outer end of the guide vane member is supported at the outer wall structure. The inner wall structure (12) and the outer wall structure (11) are jointly provided as a vane carrier unit (1), wherein the inner wall structure and the outer wall structure are fixedly connected to each other by at least one bridging member (13) extending between the inner wall structure and the outer wall structure, and wherein the bridging member is provided upstream the downstream end of the duct with respect to the main working fluid flow direction.
